| |
| Changes since the last public release (1.4.4): |
| |
| Fixed possible configure.ac bug introduced in version 1.4.4. |
| Wrapped long lines in CMakeLists.txt and introduced ${libpng_public_hdrs} |
| Check for out-of-range text compression mode in png_set_text(). |
| Removed some extraneous parentheses that appeared in pngrutil.c of |
| libpng-1.4.3 |
| Revised png_get_uint_32, png_get_int_32, png_get_uint_16 (Cosmin) |
| Moved reading of file signature into png_read_sig (Cosmin) |
| Fixed atomicity of chunk header serialization (Cosmin) |
| Added test for io_state in pngtest.c (Cosmin) |
| Added "#!/bin/sh" at the top of contrib/pngminim/*/gather.sh scripts. |
| Changes to remove gcc warnings (John Bowler) |
| Certain optional gcc warning flags resulted in warnings in libpng code. |
| With these changes only -Wconversion and -Wcast-qual cannot be turned on. |
| Changes are trivial rearrangements of code. -Wconversion is not possible |
| for pngrutil.c (because of the widespread use of += et al on variables |
| smaller than (int) or (unsigned int)) and -Wcast-qual is not possible |
| with pngwio.c and pngwutil.c because the 'write' callback and zlib |
| compression both fail to declare their input buffers with 'const'. |
| Added comment about the potential API incompatibility of the |
| png_get_uint_16() macro with libpng-1.4.0 through 1.4.4. |
| Removed PNG_NO_WRITE_GAMMA from pngminim/encoder/pngusr.h |
